Businesses increasingly use data across all sectors to make crucial business choices, such as which new goods to create, which new markets to join, which new investments to make, and which new (or current) clients target. They also utilize data to discover inefficiencies and other issues that the firm needs to address.

The data analyst’s task in these companies is to provide a numerical value to these critical business operations to measure and compare performance across time.
